Even before the Spanish conquest did this crop play an important role in high Andean production systems and in feeding the indigenous population [2]. Among legumes, the lupine is characterised by its high-quality protein content, suitability *Corresponding author: Marten Sørensen, Department of Plant & Environmental the Andean region, the annual per capita consumption varies, e.g., in Ecuador, it is 4 to 8kg Sciences, University of Copenhagen, for environmentally-1 robust production, and potential-1 health benefits [3].

Furthermore, in addition to its high alkaloid attacks [12]. The presence of these alkaloids in the seeds and the low yields (800-1,300kg ha-1) have strongly limited the expansion of this crop [13,14]. Efforts have been made to reestablish lupine as a crop in South America and to adapt it to conditions in Europe [15]. The Andean lupine is characterized by the highest grain quality of all cultivated lupines, presenting an oil content similar to that of soybeans (Glycine max (L.) Merr.) [16]. Numerous a wide range of possible products ranging from proteins, oils and food additives to cosmetics, studies investigating the nutritional profile and potential applications of this pulse have found medicines and biopesticides. Also, the nutritional advantages make it an ideal product for the transition from meat-intensive diets to diets based on vegetable proteins [16].

Germplasm collections The use of RADseq in the analysis of this archaeological material L. mutabilis Blanco at the University of Cusco (Peru) and soon spread to region (northern Peru), from the wild progenitor L. piurensis C.P.Sm. The germplasm collections were started in 1974 by Dr Oscar confirms that was first domesticated in the Cajamarca Demographic analysis suggests that L. mutabilis separated from its more than 3,000 Andean lupine genotypes. The largest and most parent around 2600BC and suffered a bottleneck in domestication, Bolivia and Ecuador; Currently, South American institutions have relevant germplasm collections of L. mutabilis are found in the with subsequent rapid population expansion as it was cultivated gene banks of Peru, Ecuador and Bolivia.

Regarding the Ecuadorian collection of Lupinus, the National Institute for Agricultural Research (INIAP) has a collection of relatives that show diversity and variability found in the Andean approx. 530 accessions of which about 70% belong to L. mutabilis In the Andean region 83 species have been identified; the wild lupine are the following species: Lupinus ananeanus Ulbr., L. aridulus Sweet (Table 1).

Three geographically separated morpho-types of the Andean The presence of considerable variation in germplasm is shown lupine have been suggested based on the considerable genetic by different phenotypic traits, such as a wide range of growth and morphological variability and wide ecological adaptation in the Andean zone: a) Lupinus mutabilis, lupine (northern Peru and periods, branching patterns, colour and shape of grains and flowers, (ISSR) and Single- Sequenced Repeat (SSR) markers have revealed as well as flowering times.

High diversity seed The requirement for lupine is variable, depending on the soil, characteristics include shape (lenticulate to spherical), primary temperature and wind. It grows well in temperatures from 20 to 25 o oC (night temperature), can range from pearly white to solid black and includes beige/ C; grain development is optimal below 9.5 and secondary seed colour, as well as distribution patterns; colour ecotypes of Puno-Peru, needs 450mm of precipitation per crop yellow, brown, dark brown, and colors in between such as brownish a condition that occurs in the high Andean region [23]; the early green and greyish green. Most of the seeds have a secondary colour cycle, while the late ecotypes require between 600 and 700mm [13].
